In a statement, Intermediate School District 917 Superintendent Mark Zuzek wrote that the staff member did not make the post on Twitter while at school, and “there were no school devices, equipment or other school staff involved in the actions.”

“At no time were students or staff in danger. The employee was placed on paid administrative leave and an investigation conducted.”

Complaints about the statement started appearing on Sunday, school officials said.

The teacher has not been charged with a crime.

The Rosemount district serves special education students in nine public school districts across the southeast metropolitan Minneapolis area. It is separate from the Rosemount-Apple Valley-Eagan school district, the Star-Tribune said.
